Mix together pork, peppers, onion, garlic, cumin and salt into the pressure cooker. Put on lid and place over high heat until up to pressure. Once up to pressue, cook for 30 minutes. Carefully release pressure. Remove the large pieces of pork and set aside. Add in the cilantro and fish sauce and blend together. I used my immersion blender which was very convenient, but you could use a blender if you needed to. Return pork to sauce and stir to combine. Serve with tortillas and lime wedges.

I also added chopped veggies to the top as well. Onions, sweet peppers and avocado.
